My choice is Echo saws.I have two that start easy and run well.My stihl saws started to hard and they come with the PIA filler caps.Here's my dilemma: My Stihl 031 that I bought new in 1978 finally bit the dust after many years of noble service. It was one heck of a rugged saw. So, I'm looking for a replacement and have been perusing websites and a couple of local dealers. What I've found fills me with unease. The current stock seems much less robust - lots of plastic, and I've heard grumbles about poor customer service, specifically regarding Husqvarna. So, what to do?![]()
The 4-mix are valved 4stroke engines running an oil/gas mix so they don't need crankcase oil. This saves weight and they are mostly on the Stihl trimmer line. Some of the newer Sthil chainsaws are strato saws and are still 2stroke. The strato technology allows the saw to take a "gulp" of fresh air between the strokes to better separate the exhaust air from the fueled air. Bad explanation, I know.

Seams like a backwards way of doing things. What's the point of a 4 stroke if you are burning oil? The small Honda engines use crankcase oil but once the engine starts the oil vaporizes so the engine can run at any angle and still get lubricated. My string trimmer has a Honda 35cc 4 stroke engine and runs great. They even use the Hondas in remote control planes that fly upside down.
